BMI 的單位----來自WHO答案

Body Mass Index (BMI) is a simple index of weight-for-height that is commonly used to classify underweight, overweight and obesity in adults. It is defined as the weight in kilograms divided by the square of the height in metres (kg/m2). For example, an adult who weighs 70kg and whose height is 1.75m will have a BMI of 22.9.

• 謝謝, 我從來不知道BMI是有單位的. 如何理解index可以有單位? -花椒- ♀ (0 bytes) () 12/22/2014 postreply 14:52:37

• INDEX都是比值，直接用原來的單位都很難明白啥意思。一般都是重新定義一個新單位，例如帕斯卡，牛頓這些單位都是這麽來的，用習慣就 -ephd- ♂ (0 bytes) () 12/23/2014 postreply 06:08:37
